SPECIFICATION forming part of Letters Patent No. 783,877,

dated February 28, 1905.

Application filed August 23, 1904. Serial No. 221,813.

To t wit/mt may concern:

Be it known that l, Rum-inn Jenn Linus, a subject of the King of Great Britain, residing at Northampton, England, have invented certain new and useful improvements in W ood- Cutting Machines, of which the following is a specification, such as will enable those skiiled in the art to which it appertains to make and use the same.

This invention relates to machines for cutting wood; and the object thereof is to provide an improved machine of this class which is designed for use in cutting wood for various purposes, such as the making of various kinds and classes of furniture and for making boxes of various shapes or forms, a further object being to provide a machine of the class specilied which is particularly designed for cutting wood, boards, or lumber at any desired angle and for making miter-frames, )iCl3LU'O-flflll18$, and for various other purpose.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, in which.

Figure 11. is a plan view of my improved wood-cutting machine; Fig. 2, a front view thereof, partially in section; Fig. 3, a back view, partially in section; Fig. f, a left-hand side elevation; Fig. 5, a section on the line 5 5 of Fig. 2; Fig. 6, an inside view of an adjustable bearing-block, one of which is employed at each end of the machine; and Fig. 7, an outside view of a rotatable disk, one of which is employed at each end of the machine and used in connection with the bearingblocks, one of which is shown in Fig. 6, said disk or disks being employed for the purpose of tilting the cutting tool or tools.

in the practice of my invention l provide a rigid main frame comprising side plates or members (I, connected at the back by a bar a and in the bottom rear portion by a bar it, these parts being clearly shown in Figs. '1, 2, 3, 4-, and 5. Each of the side plates (0 is provided in the rear top portion thereof with an angular recess 0, the outlines of which are formed by the lines If and 0", f)" and b", and /1' and If, as cl early shown in full lines in Fig. 5 and in dotted lines in Fig. i, and each of the side plates or members it is provided with a bearing-box c, an inside view of one of which given in Fig. 6, and these bearing-boxes are connected with the outside thereof so as to .cover the recesses 7), this connection being made by means of bolts 0 which pass through. said bearing-boxes and through the side plates or members a, and the holes c in the bearingboxes 0, through which the bolts 0 pass, are made oblong, so as to permit of the slightforward and backward zuiljustl'nent of said bearing-boxes, and each of said. bearing-Mixes is provided at its front end with a screw c, which is rigidly connected therewith, and the screws 0 pass through keepers c, formed on or connected with the side plates or members a of the main frame, and the screws 0 are provided at the opposite side of the keepers c with setnuts 0, and by means of this construction the bearing-boxes 0 may be adjusted within certain limits forwardly and backwardly of the main frame. The bearing-b0xes c are also provided centrally thereof with a verticallyarranged oblong and rectangular opening 0 and in the inner side thereof with segmental grooves c, three of which are shown, and these grooves 0 open upwardly, and said bearing-boxes are also provided in their upper edge and midway thereof with a l/shaped recess c".

In the bearing-boxes c and held therein by the side plates or members of the main frame are placed rotatable disks (6, an inside view of one of which is given in Fig. 7, and thesedisks (Z are provided with concentrically-arranged ribs which litin the grooves o inthe bearlug-boxes c, and said disks are each provided in the bottom half thereof with a segmental opening (Z and in the top thereof with a vertically-arranged oblong rectangular mvening (1, provided with a backwardly-directed angular recess and said disks (1 are also pro vided rearward] y of the openingrl" with screw or bolt holes The main frame is provided with a table 1/, which forms a part of the main frame and which extends backwardly to the recess 6 in the side plates or members 1/ of the main frame, and when the bearing-boxes c are in position they extend to the top of the table a, as shown in Figs. 2 and 4c, and the diameter of the rotatable disks (Z is substantially twice that of the vertical width of the bearingboxes 0, and said rotatable disks extend a distance above the table at equal approximately to one-half of their diameters.

The rotatable disks (Z are rigidly connected by a horizon tally and vertically arranged plate 0, having angular end members (2 which are bolted or secured to said disks by means of bolts orscrews which pass through said angular end members e of the plate (2 and through the holes d" in the disks (Z, and the front side or surface of said plate 0 is flush with the rear walls of the openings (1 in said disks, and said plate 0 is provided in the front top portion thereof with a longitudinal groove 0* and in the bottom portion thereof with a longitudinal slot 0".

Mounted centrally on the plate 0 is an angular keeper which is secured thereto by bolts or screwsf' -and which extends a predetermined distance in front of said plate, and mounted on the keeper 7" is another angular keeper g, which extends backwardly of the plate a and is provided with a depending member g and with inwardly-set end ears g, by which it is bolted to the plate a, this construction being clearly shown in Figs. 1, 2, 3, and 4, and the keeper g is provided with an up wardly-directed hub orbearing f, in which is mounted a vertically-arranged spindle the upper end of which is angular in form, as shown at g, and adapted to receive a crank or other operating device and the lower end of which is provided with a gear or pinion g and the plate a is cut out in the top thereof, as shown at e in Fig. 5, to receive the pinion or gear g Mounted in front of the plate a and passing through the keeperf' is a rackbar it, which is adapted to be operated by the pinion or gear g and the bottom of said bar is provided with a downwardly-(iirected member 71?, to which the cuttingblades b" are secured, said blades being secured to said member by bolts or screws 72;. The opposite ends of the member if converge downwardly from the rack-bar h and range at an angle of about forty-five degrees thereto, and the edges If of the cutting-blades it converge at a similar angle.

Mounted in the longitudinal slot (1 in the plate a is a slide 2', to which the downwardlydirected member [L2 of the rack-bar la is bolted, as shown at z? in Figs. 3, at, and 5, and the slide 1' is provided at the back of the plate 6 with downwardly and upwardly directed flanges 1 and by this means the rack-bar and the member 702 thereof, to which the cuttingblades 7L3 are secured, is firmly held in place andat the same time free to more longitudinally of the plate a, and the bottom screws or bolts, which hold the cutting-blades h in position, or the ends thereof, also enter and move in the longitudinal slot in the plate a, while the top screws or bolts, used for holding the said cutting-blades in position, or the rear ends thereof, fitand move in the longitudinal groove in the plate at.

In the bottom portion of the main frame and arranged centrally of the bearing-boxes 0, is a horizontal shaft j, composed of two parts f, and the opposite ends of which are provided with reversed threads, as shown at f, and the ends of this shaft pass through segmental blocksj", mounted in the segmental recesses d" in the rotatable disks (Z, and which serve to limit the movement of said disks, and the ends of said shaft also pass through nuts f, which fit in the rectangular openings 0 in the bearing-boxes c, and one end of said shaft is provided with a crank j, and the ends of said shaft on the inner sides of the side plates or members a of the main frame are also provided, in the form of constructionshown, with locking-nutsj which may or may not be employed. The separate parts of the shaft j are connected centrally thereof by a sleeve f in the form of construction shown; but this connection may be made in any desired manner, and the object of the shaft j is to provide means for holding the rotatable disks (Z in proper position and in contact with the side plates or members a of the main frame, and also to provide means for limiting the rotation of said disks in either direction.

I have also shown at I: a work-piece, or a board which it is designed to cut, and this board is placed on the table a at one side of the machine, and the rear edge thereof is moved backwardly to the rear edge of said table, and in practice the spindle is turned by the crank 75 or in any desired manner, and this operation moves the rack-bar it in the desired direction or toward the board 7r, according to the direction in which the spindle is turned, and the rear edge or side of the board Z: will be cut off by the blade or blades it. and the angle of the cut will depend on the position of the plate a. It will be understood that the plate a, which carries the rack-bar h and blades 71f, may be turned forwardly or backwardly within certain limits to any desired angle, and this will not interfere with the operation of the rack-bar it and the blades [L3, and the edge or side of the board it may be cut off at any desired angle within certain limits, and when the said plate a and rack-bar it are swung backwardly the angular members at the end of the plate 0 move in the recesses L in the end plates or members a of the main frame, and the recesses a" in the top portions of the bearing-boxes c are intended to permit of the passage of the bottom portion of the member 71. which carries the cutter-blades h", and also the bottom portions of said cutter-blades, it being understood that the rackbar 71., together with the cutter-blades hf, may be projected beyond either side of the machine in the op eration thereof, and in Fig. 3 said parts are shown projected to the left. It will also be understood that the work-piece A? may be placed at either side of the machine, and. in practice is usually placed at one side and then at the other, and it will also be rmderstood that the plate a may be held at any desired angle for any necessary time, and the machine may be operated by one man, who holds the work-piece l with one hand and holds the crank which operates the spindle 7" with the other hand.

Constructed as hereinbefore described, it will be seen that the leading features of my improved wood-cutting machine consist of a main frame having a front table vertically arranged and rotatable disks mounted at the ends of the main frame and connected by a horizontally and vertically arral'iged plate forming a support for the rack-bar, a rackbar mounted in said support and provided with depending cutter-blades, and means for operating said rack-bar and other means for holding the rotatable disks at any desired point.

My invention is not limited to the exact details of the construction herein shown and described, as many changes therein and modifications thereof may be made without departing from the spirit of my invention or sacrilicing its advantages, and l reserve the right to make all such alterations therein as fairly come within the scope of the invention.
